Haehnel, Reading, Pa., assignor to Textile Machine Works, Wyomissing, Pa., a corporation of Pennsylvania Filed Feb. 2, 1967, Ser. No. 613,523 Claims. (Cl. 66-155) ABSTRACT OF THE DISCLOSURE The invention disclosed herein relates to straight bar or full-fashioned knitting machines for knitting flat fabric blanks and more particularly to pattern mechanism for controlling the knitting cycles of the machine to form the knitted courses of the fabric blanks, and the stitch transferring cycles of the machine to fashion and to form lace stitch patterns in the fabric blanks.

Background of the invention Field of the invenlion.--The invention is specifically directed to the pattern mechanism of a full-fashioned knitting machine including a main pattern device for controlling the machine in knitting cycles for forming courses of flat fabric blanks and in stitch transferring cycles for fashioning the selvages of the fabric blanks, an auxiliary pattern device for controlling the machine in stitch transferring cycles for forming lace stitches in the fabric courses, means operated by the main pattern device for inactivating the operating means for the auxiliary pattern device during operation of the main pattern device, means operated by the auxiliary pattern device for inactivating the operating means for the main pattern device during oper ation of the auxiliary pattern device, and means operated by the main pattern device for preventing operation of the inactivating means for the main pattern device by the auxiliary pattern device to permit both main and auxiliary pattern devices to control stitch transferring cycles of the machine in fabric courses having both selvage fashioning and lace stitch formation.

Description of the prior art.Heretofore a full-fashioned knitting machine for knitting fiat fabric blanks was provided with main and auxiliary pattern devices, such as shown in US. Patent No. 2,516,514, with the main pattern device controlling the operation of the machine in knitting cycles and stitch transferring cycles to fashion the fabric blanks and the auxiliary pattern device controlling the operation of the machine in knitting cycles for inserting additional courses in the fabric blanks to change the size thereof and also controlling certain of the stitch transferring cycles of the machine to fashion the fabric blanks. The main pattern device operated means for inactivating the auxiliary pattern device and the auxiliary pattern device operated means for inactivating the main pattern device. Where the fabrics formed on the machine were to be fashioned and also provided with lace stitch formations, the machine was provided with main and auxiliary pattern devices generally of the type shown in US. Patent No. 2,182,220 with the main pattern device controlling the stitch transferring cycles of the machine to fashion the fabric selvages and inactivation of the narrowing head mechanism during stitch transferring cycles to form lace stitches and the auxiliary pattern device controlling the stitch transferring cycles to form the lace stitches. The auxiliary pattern device was inactivated by the main pattern device during operation of the main pattern device. During the operation of the auxiliary pattern device to control the lace mechanism and the stitch transferring cycles of the machine for the lace formation the main pattern device also remained in operation to count the 3,415,082 Patented Dec. 10, 1968 ICC stitch transferring cycles of the machine controlled by the auxiliary pattern device.

Hence, while the prior art provided main and auxiliary pattern devices with means for inactivating each pattern device from the other and provided for the control of stitch transferring cycles of the machine for fabric fashioning from one pattern device and stitch transferring cycles for forming lace designs in fabrics from the other pattern device, it did not provide for the operation of each of the pattern devices without the other to control the machine for stitch transferring cycles for fabric fashioning and lace formation or the operation of both pattern devices to control a stitch transferring cycle of the machine in which both fabric fashioning and lace formation occur.

Summary of the invention Briefly summarized the invention resides in the provision of pattern mechanism for a full-fashioned knitting machine including a main pattern device for controlling knitting cycles and stitch transferring cycles of the machine for fabric fashioning and an auxiliary pattern device for controlling stitch transferring cycles of the machine for lace formation. The invention further resides in means for inactivating the auxiliary pattern device during operation of the main pattern device, means for inactivating the main pattern device during operation of the auxiliary pattern device, and means for controlling the inactivating means for the main pattern device whereby both main and auxiliary pattern devices are operated to control stitch transferring cycles in which both fabric fashioning and lace formation occurs.

Description of the preferred embodiment Referring to the drawings there is shown a portion of a full-fashioned knitting machine for knitting fiat selvaged fabric blanks, including a front beam 10, one of the center frames 11 (FIG. 1) which together with end frames and other beams and beds (not shown) form the conventional framework of the machine, a camshaft 12 mounted for rotation in the center and end frames, a main pattern device 15, which is adapted to control the operation of the machine during knitting cycles and during stitch transferring cycles to fashion the selvages of the blanks, and an auxiliary pattern device 16 which controls the operation of lace point mechanism (not shown) and institutes stitch transferring cycles of the machine to form lace designs in the fabric blanks. The main pattern device 15 shown herein for purposes of illustration is a conventional chain device and includes a pattern chain 17 which is trained over a driving sprocket wheel 20 and idler sprockets (not shown) in the usual manner. The sprocket wheel 20 is mounted for rotation on a stub shaft 21 secured in fixed position on a bracket 22 carried on the front beam 10. Secured to the sprocket 20 is a ratchet 25 the teeth of which are adapted to be engaged by a pawl 26 (FIG. 4). The

pawl 26 is pivotally mounted on a lever 27 which is mounted for oscillating movement on the shaft 21. Except as hereinafter set forth, the lever is oscillated to operate the pawl 26 through strokes to advance the ratchet and sprocket 20 by a cam lever 31 which is operated by a cam (not shown) on the camshaft 12 during each revolution of the camshaft. A spring 30 connected between the paWl 26 and lever 31 biases the pawl toward engagement with the ratchet 25 and a spring 32 connected between the lever 27 and a fixed part of the machine tends to turn lever 27 counterclockwise as viewed in FIG. 4 toward engagement with the lever 31.

The main pattern device 15 also includes a shaft 33 which is mounted for axial shifting movement in the bracket 22 to move a roller type follower (not shown) on the shaft from a position in alignment with a cam face 35 (FIGS. 1 and 3) on the camshaft 12 in which the cam face 35 and follower coact to axially position the camshaft for knitting cycles of the machine and to a position in alignment with a cam face 36 on the camshaft in which the cam face 36 and follower coact to axially position the camshaft for stitch transferring cycles of the machine. The shaft 33 is normally held in position to align the follower thereon with the cam face 35 by engagement of a nose portion 37 of a latch lever 40 in an annular groove 41 in the shaft (FIG. 3). The latch lever 40 is pivotally mounted on a stub shaft 42 carried in the bracket 22 and the latch lever is biased in a clockwise direction by a spring 45 to engage the nose portion 37 in the groove 41 in the shaft 33 and is turned in a counterclockwise direction to release the nose portion from the groove to permit axial movement of the shaft to align the follower thereon with the cam face 36.

The latch lever 40 is turned counterclockwise to release the shaft 33 by buttons on the chain 17 which act through connections including a pattern lever 46, which is one of the usual levers associated with the main pattern device 15, pivotally mounted on the shaft 42. The lever 46 has a nose 47 (FIG. 3) for engaging one arm 50 of a lever 51 pivoted on a pin 52 in a bracket 55 (FIG. 1) supporting the outer ends of the shafts 21 and 42. A second arm 56 of lever 51 carries an adjustable stop screw 57 for engagement with an arm 60 of a lever 61 pivotally mounted on the pin 52. A second arm 62 of lever 61 carries a pin 65 for engagement in an open end slot 66 in one end of a link 67. The other end of link 67 is pivotally mounted on a stud 70 carried in the latch lever 40 and a spring 71 connected between the latter end of the link and the upper end of arm 62 of lever 61 tends to bias the pin 65 against the end of the slot 66 in the link 67. When a button on the chain 17 is moved beneath lever 46, the lever 46 acts through lever 51 to turn lever I 61 counterclockwise, as viewed in FIG. 3, and at this time the spring 71 permits relative movement between the link 67 and pin 65. When pressure of the shaft 33 is relieved on the nose portion 37 of latch lever 40 by a cam (not shown) provided on the camshaft for moving the shaft 33 and the follower thereon from alignment with cam face 36 into alignment with cam face 35, spring 71 then acts to turn the latch lever counterclockwise to disengage the nose portion from the shaft thereby permitting it to move the follower into alignment with cam face 36 to shift the camshaft toward the right for a stitch transferring cycle.

Also associated with the main pattern device 15 is a switch indicated generally at 73 in FIG. 1 which is connected into the motor circuit of the machine to slow the speed of the motor during stitch transferring cycles of the machine to fashion the fabric in a conventional manner. The switch 73 is connected by a rod 74 to one of the pattern levers of the device 15 and the pattern lever is operated by a button on the chain 17 to operate the switch and slow the motor speed slightly in advance of the operation of the button controlling shifting of the camshaft for a stitch transferring cycle to fashion the fabric.

The auxiliary pattern device 16 shown herein is also a conventional chain device and includes a pattern chain 72 which is trained around a sprocket wheel 75 (FIG. 1) and a series of idler wheels (not shown). The sprocket wheel 75 is mounted for rotation on a stub shaft 76 carried in a bracket 77 secured to the front beam 10. The sprocket wheel 75 is provided with a ratchet 80 the teeth of which are adapted to be engaged by a pawl 81 pivotally mounted on a lever 82 mounted for oscillating movement on the shaft 76 (FIG. 2). The lever 82 is oscillated by a cam lever 85 which is operated by a cam on the camshaft (not shown) during each revolution of the camshaft to operate the pawl 81 and advance the ratchet 80 and sprocket 75, when the pawl is permitted to engage the teeth of the ratchet. A spring 86 connected between the pawl 81 and lever 85 biases the pawl toward engagement with the ratchet 80.

The auxiliary pattern 16 is idled during operation of the machine in knitting and stitch transferring cycles of the machine controlled by the main pattern device 15 to fashion the selvages of the fabrics and the device 16 is then started and operated to control the operation of the lace mechanism and the stitch transferring cycles of the machine to form the lace design. The means for idling and operating the pattern device 16 is of the type shown and described in U.S. Patent No. 2,516,514 and includes a control member in the form of a second ratchet 87 which is rotatably mounted on the shaft 76 adjacent the ratchet 80. The ratchet 87 is provided with portions 90 for blocking teeth of the ratchet 80, to at times prevent engagement of the pawl 81 therewith, alternating with spaces which permit engagement of the pawl with the teeth of the ratchet. A spring pressed detent 91 carried in the lever 82 and engaging the teeth of ratchet 87 acts to idly advance and again return the ratchet a distance of one tooth during each oscillating movement of the lever 82 by the sam lever 85, unless the return movement of the ratchet 87 is prevented, as hereinafter set forth. When a blocking portion 90 is beneath the nose of pawl 81, the ratchet 87 and blocking portion are moved with the pawl 81 to maintain it out of engagement with the ratchet 80 during both advancing and return move ments of the lever 82. On the other hand when the nose of the pawl 81 is in the space between a pair of blocking portions 90 and in engagement with a tooth of ratchet 80, movement of the ratchet 87 with the pawl 81 permits the pawl to advance the ratchet 80 one tooth in forward strokes and permits the pawl to engage another tooth in return strokes during each oscillating movement of lever 82.

The means for causing the detent 91 to advance the ratchet 87 to move a blocking portion 90 beneath the pawl 81 to prevent it from engaging and advancing the ratchet 80 or to move a space beneath the pawl 81 to permit it to engage and advance the ratchet 80 includes an arresting lever 92 pivotally mounted on a pin 95, carried in the bracket 77, the arresting lever having a nose 96 adapted to engage the teeth of ratchet 87. The lever 92, pivotally carries a stud 97 having a hole for receiving one end of a rod 100 between a collar 101 fixed on the rod 100 and a collar 102 slidably mounted on the rod (FIG. 2). A compression spring 105 mounted on the rod 100 between the collar 102 and a collar 106 fixed on the rod biases the collar 102 into resilient engagement with the stud 07 for purposes hereinafter set forth. The other end of rod 100 is pivotally connected to a pattern lever 107 pivoted on the shaft 42. When a button 108 on the chain 17 is moved beneath lever 107 it is moved clockwise, as viewed in FIG. 3 to move the rod 100 and lever 92 toward the left to engage the ratchet 87 to prevent its return movement with the detent 91 to permit the pawl 81 to advance the ratchet 80 or to inactivate the pawl 81 in the manner above set forth. When the ratchet 87 is positioned to control the pawl in the desired manner the arresting lever 92 is disengaged from the ratchet by removing the button on the chain 17 from beneath the pattern lever 107 or by other means hereinafter described.

During formation of lace designs and particularly such lace designs requiring a plurality of successive stitch transferring cycles of the machine to form each lace stitch course of the design, the auxiliary pattern device 16 is started by the main pattern device 15, as above set forth, and groups of buttons 110 provided on the chain 72 of device 16 act to operate the lever 40 to release the shaft 33 to shift the camshaft 12 for the required stitch transferring cycles, the buttons also acting at this time to idle the main chain device in the manner hereinafter set forth. Following the required number of stitch transferring cycles the main pattern device 15 is again started to count the plain knitted courses to the next course having lace stitches and the auxiliary pattern device 16 is stopped and the two pattern devices then operate alternately to form the lace stitch design with the main chain device controlling the knitted courses and the auxiliary chain device controlling the successive stitch transferring .cycles required to form the lace stitch design.

\ For operating the lever to cause shifting of the camshaft for stitch transferring cycles to form lace stitch courses as above set forth, the buttons 110 on chain 72 are adapted to act on a lever 111 pivotally mounted on a shaft 112 carried in the bracket 77. The lever 111 has an upwardly extending arm 115 pivotally connected to one end of a rod 116 the other end of which is pivotally connected to an arm 117 of the lever 61. When the buttons 110 are moved into engagement with lever 111 it is turned clockwise as viewed in FIG. 1 to move rod 116 toward the right and turn lever 61 counterclockwise, the latter lever then acting through spring 71 to turn lever 40 counterclockwise to disengage the nose portion 37 thereof from shaft 33 to permit movement of the shaft to shift the camshaft 12 to stitch transferring position.

Upon movement of the rod 116 to the right by the first of a group of buttons 110 to cause shifting of the camshaft 12 for stitch transferring cycles as above set forth a finger 120 secured on the rod is moved to engage a pin 121 on the arresting lever 92 to disengage the arresting lever from the ratchet 87. Since at this time a button 108 on the chain 17 is still beneath the lever 107 to hold the rod 100 in its left position to engage the arresting lever 92 with the ratchet 87, movement of the arresting levre by the finger 120 to disengage it from the ratchet is relative to the rod 100 against the action of collar 102 and spring 105 on the rod.

Also upon movement of the rod 116 to the right by the first and following buttons of the group of buttons 110 for causing shifting of the camshaft for stitch transferring cycles the lever 27, after being raised by cam lever 31 to operate pawl 26 to advance the ratchet 25 and chain 17 a distance of one tooth of the ratchet, is arrested in its downward movement to idle the pattern device 15. For this purpose an arresting lever 122 is moved beneath a pin 125 carried in the lever 27 (FIG. 4). The lever 122 which is pivotally mounted on a stud 126 carried in a bracket 127 secured to the front beam 10, is pivotally connected to one end of a rod 130. The other end of rod 130 is mounted for sliding movement in a bearing member 131 secured to rod 116 as by set screw 132 (FIG. 2). A collar 135 secured to rod 130 is held in releasable engagement with one side of the bearing member 131 by a coil type compression spring 136 carried on the rod 130 between the opposite side of the bearing member from collar 135 and a second collar 137 secured to the rod 130.

Also during movement of the rod 116 to the right to shift the camshaft 12 for stitch transferring cycles cam followers (not shown) associated with the operating means for the narrowing head mechanisms are normally shifted to inactive position to inactivate the narrowing head mechanisms. The mechanism for this purpose is generally of the type shown and described in US Patent No. 2,182,220 and includes follower shift levers similar to the lever 272 of said patent which are connected by a 6 rod to a cam lever, a portion of which is shown at 150 in FIG. 1, for operating the shift levers to shift the cam followers to inactive positions. The lever 150 is maintained inactive by a support lever 151 (FIG. 1) pivoted on the shaft 112 when the camshaft is shifted to stitch transferring position by the main pattern device 15 to permit operation of the narrowing head mechanisms during fabric fashioning stitch transferring cycles. However, during operation of the rod 116 to control the stitch transferring cycles of the machine, as above set forth, the support lever 151 must be removed from beneath the lever 150 to permit its operation to shift the cam followers for the narrowing head mechanisms to inactive positions. For so operating the support lever 151 to release the lever 150, the support lever is connected by a link 152 to one arm 155 of a lever 156 pivotally mounted on a fixed part 157 of the framework of the machine. A second arm 160 of the lever 156 is pivotally connected by a link 161 to the arm 115 of lever 111. Hence, when the lever 111 is operated by buttons 110 on chain 72, the lever acts through links 152, 161 and lever 156 to move the support lever 151 from beneath the lever 150 thereby permitting lever 150 to be operated to inactivate the narrowing head mechanisms, unless otherwise prevented from doing so as hereinafter set forth.

Normally when the auxiliary pattern device 16 is to be started to control the successive stitch transferring cycles of the machine to form lace stitch courses, a button 108 is moved beneath the lever 107 to move the rod toward the left as viewed in FIG. 2 to engage arresting lever 92 with the teeth of ratchet 87 to arrest the return movement of ratchet 87 with detent 91 thereby removing an idling portion 90 of ratchet 87 from beneath the pawl 81. During the next operating movement of pawl 81 the ratchet 80 is advanced to move the first of the group of buttons on the chain 72 beneath the lever 111 to turn it clockwise thereby moving the rod 116 toward the right to disengage the latch lever 40 from shaft 33 to permit it to shift the camshaft 12 to the right to stitch transferring position. At this time movement of the rod 116 to the right acts through finger to disengage the arresting lever 92 from the ratchet 87 to permit pawl 81 to continue advancing chain 72 to move rod toward the right to move the arresting lever 22 from inactive to active position to arrest the operation of lever 27 and pawl 26 thereby idling the pattern device 15 while the button 108 is still beneath the lever 107. At this time movement of the lever 111 by the buttons 110 to move the rod 116 to the right also moves support lever 151 to release lever to shift the cam followers for the narrowing head mechanisms to inactive positions to inactivate the narrowing head mechanisms.

During the stitch transferring cycle controlled by the last of the group of buttons 110 on the chain 72 the pawl 81 indexes the chain to remove the last button 110 from beneath lever 111 to permit it to turn counter-clockwise and move the rod 116 toward the left to permit latch lever 40 to latch shaft 33 in position to maintain the camshaft 12 in knitting position and to move the support lever 151 beneath the cam lever 150. Movement of the rod 116 to the left disengages the finger 120 from arresting lever 92 permitting it to move into engagement with and arrest the return movement of ratchet 87 with the detent 91 to position a portion 90 beneath the pawl to idle it. Movement of the rod 116 to the left also moves the arresting lever 122 to inactive position to permit operation of the lever 27 and pawl 26 to operate the chain 17 and remove the button 108 from beneath lever 107 whereby the rod 100 is moved to the right to disengage the arresting lever 92 from ratchet 87 to idle the auxiliary pattern device 16. The main pattern device 15 then continues to operate during knitting cycles of the machine until a button 108 on chain 17 is again moved beneath lever 107 to start the auxiliary pattern device and stop the main pattern device as hereinbefore set forth.

When it occurs that the chain 17 is provided with a button to operate lever 46 to cause shifting of the comshaft 12 to stitch transferring position to fashion the selvages of a course of the fabric and a button 108 to move lever 92 into engagement with the ratchet 87 to start the auxiliary pattern device 16 to institute the series of successive stitch transferring cycles to form lace stitches in the same course, the lever 46 is operated to release latch lever 40 from the shaft 33 to cause shifting of the camshaft 12 to transferring position and the first of the group of buttons 110' operates lever 111 to shift the rod 116 to the right which would normally cause release of the latch lever from the shaft 33 and movement of the support lever 151 from beneath lever 150. This movement of the rod 116 to the right also moves finger 120 to disengage arresting lever 92 from ratchet 87 to permit continued movement of the auxiliary pattern device. However, at this time since the stitch transferring cycle to fashion the fabric is insituted from the main pattern device the chain 17 must remain in operation for this stitch transferring cycle with the auxiliary pattern device 16 and the lever 150 maintained inactive to permit the cam followers to re main in active position to operate the narrowing head mechanisms. The lever 150 is maintained inactive at this time by a second support lever 162 which is connected by a rod 165 to a lever 163 pivotally mounted on the pin 52 and having an arm 164 (FIG. 1) adapted to be acted on by one of the pattern levers associated with the main pattern device 15. When buttons on the chain 17 shift the camshaft 12 .and start the auxiliary pattern device 16 as above set forth, a button on the chain 17 also acts through lever 163 and rod 165 to move the lever 162 beneath the lever 150 before the lever 151 is moved from beneath the lever 150 by the buttons 110 on the chain 72. It is also to be noted that at this time a button on the chain 17 operates the switch 73 to slow the speed of the machine during the stitch transferring cycle to fashion the fabric.

In order to permit another index of the chain 17 at this time to remove the buttons controlling the latch lever 40, the support lever 162 and the switch 73, the arresting lever 122, which is normally moved to arrest lever 27 and pawl 26 when the rod 116 is moved toward the right, is prevented from moving to arresting position. For this purpose the rod 130 slidably supports a stop member 166 adapted to be moved into engagement with the collar 137 on the rod 130. The stop member 166 is secured to one end of a rod 167 the other end of which is pivotally connected to a lever 170 pivotally mounted on the stub shaft 42. Lever 170 carries an adjustable set screw 171 for engagement with lever 46. When the lever 46 is moved by a button on chain 17 to release shaft 33 for a stitch transferring cycle, lever 170 is turned clockwise as viewed in FIG. 3 to push rod 167 to the left to move stop member 166 into arresting engagement with the collar 137 on the rod 130. Thereafter, when rod 116 moves to the right under the influence of the buttons 110 on chain 72, the bearing member 131 moves relative to the rod 130 to compress the spring 136. Following this stitch transferring cycle instituted by both pattern devices the pawl 26 is operated to index the chain 17 and to remove the button from beneath lever 46 thereby permitting the lever 170 to move rod 167 and stop member 166 to the right from arresting engagement with the collar 137, under the influence of a spring (not shown), which in turn permits spring 136 to move rod 130 toward the right to move arresting lever 122 beneath lever 27 to idle pawl 26 and chain 17 during the remainder of the successive stitch transferring cycles instituted by the buttons 110 on chain '72.

It will be understood that the improvements specifically shown and described by which the above results are obtained can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.
